SPECIFICATION forming part of Letters Patent No. 779,935, dated January10, 1905. Application filed November 27,1903. Serial No. 182,741.

To @ZZ whom t may concern,.-

Be it known that LJAMns AHERRTOK, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain Improvements in Gas-Producers,ofwhich the following is a specilication.

The primary object of the present improvements is to provide a simpleand eficient gasproducer having means for introducing the blastnecessary for carrying on combustion at a very low pressure.

It has as further objects the ready examination and control of theaction'of the blast, the ready inspection, cleaning, and repairing ofthe blast-pipes, and facility of assemblage and dissociation of theparts.

The nature and characteristic features of the improvements will morefully appear by reference to the following description and theaccompanying drawings in illustration thereof, of which-- Figure 1represents a plan View of the base of a gas-producer having myimprovements applied thereto. Fig. 2 represents a sectional elevationthereof. Fig. 3 represents a sectional elevation illustrating theremoval and introduction of blast-pipes. Fig. 4 represents a top planView of an end of the blastpipe. Fig. 5 represents an end elevation ofthe construction shown in Fig. 4. Fig. 6 represents a longitudinalsectional View of the construction shown in'Fig. 4, and Fig. 7represents a transverse sectional view taken through the air-ports ofthe blast-pipe.

As shown in the drawings, the producerbody l is supported upon theseparated ringsections 2, each comprising' a horizontal web or base 2ufor supporting the weight of the producer-body, a verticaliange 2b forthe lateral support of the producer-body, and a connection for thesheet-iron shell 1a and a conical iiange 2 for supporting the conicalashhopper or base 3, the sectional rings being supported by the struts4, carried by the foundation 5.

Passing through and supported by the ashhopper 3 or the base of theproducer-body are the blast-pipes 6, which rest inthe collars 7,

secured to the base or hopper, the pipes having the lateral ports 8,through wh ich streams of air are blown and distributed to the body` ofburning fuel contained in the producer, the pipes being suitably ofordinary straight cylindrical construction having vertical slits cut intheir sides. The open inlet end of the respective blast-pipes has ablower9 inserted therein and supported in any suitable manner, as by aspider 9a, which permits the steamnozzles 9b to draw air through thespider-openings 9C and inject it into the pipe. The blowers areconnected with the steam-pipe 10 by the branch pipes l0, through whichsteam is delivered to the blowers, the iow of steam being controlled bya manually-operated shutoff valve 11 and an automatic reducingvalve 11,which may be set to maintain the desired pressure. The gages 12 and 12,attached to the pipe 10, show the pressure on either side of theautomatic valve, which may be adjusted with relation thereto. A cock1l", connected to an extension of the pipe 10 below its connection withthe pipes 10, serves to test the steam and as an outlet for products ofcondensation. By these means the injection of air into the blast ortwyer pipes 6 and thence through their ports 8 into the body of burningfuel may be regulated and maintained at the comparatively low pressureunder which the apparatus is designed to operate. The outer ends of thepipes are respectively fitted with the sleeves or flanges 13, which havethe gates or cap-plates 14 pivotally connected thereto by bolts 15, thegates having the latches 16, which respectively engage with the hasps orstuds 17, carried by the flanges. These gates permit ready access to theinteriors of the pipes for inspection, cleaning, or repairing. Each gateis provided with a valve or cock 18 for testing the blast or action ofthe air in the pipe.

The ash-hopper 3 preferably projects into a pit or basin 19, adapted forsealing the bottom of thehopper, and the pit contains the pedestal 2Ofor acting as an abutment against which to shovel in removing the ashes.

It will be observed that this construction permits the ready removal andinsertion of pipes without disturbing the contents of the producer bymerely connecting together the ends of the pipe to be removed and thepipe to be inserted by a collar 6, and the blower 9 having beendisconnected, pushing the one pipe out and the other one in through thepath vacated by the outgoing pipe, the sleeve 13, with the mechanismcarried thereby, being removed for this purpose. It will also beobserved that the blast-pipes pass through the base or ash-hopper abovethe bottom thereof and that the air is introduced wholly within theproducer-body above the bottom of the ash-outlet, by which all of theair necessary for complete combustion is introduced at a very lowpressure and without waste and is uniformly distributed to the body ofburning fue Having described my invention, I claim l. A gas-producerhaving a blast-pipe extending across the base thereof, said pipe havingone end connected with a blower and the other end provided with atest-valve, substantially as specified.

2. A gas-producer having a blast-pipe whose ends project beyond theproducer-base, blastports along the sides of said pipe, a blowerconnected with one end of said pipe, and a revraess y movable capclosing the other end thereof, substantially as specified.

3. A gas-producer having a hopper, and parallel pipes extending into andthrough said hopper,said pipes having blast-ports dischargifng1 withinsaid hopper, substantially as speci- 4E. A gas-producer having astraight blastpipe of circular cross-section extending into and throughthe base thereof, said pipe being supported by said base and havingblast apertures along the side thereof, substantially as specified.

5. A gas-producer having a base, collars carried by said base, andparallel straight blast-pipes of circular cross-section extendingthrough said collars and base, said pipes having lateral ports alongtheir lengths discharging above the outlet from said base, substantiallyas specilied.

In testimony whereof I have hereunto set my hand, this 21st day ofNovember, A. D. 1903, in the presence or' the subscribing witnesses.
